Problems solved by technology

At present, the formaldehyde removers on the market can be basically divided into four categories: sealed formulations, which temporarily cover and seal formaldehyde, but are easily damaged and released again; oxidizing agents, which oxidize free formaldehyde molecules, but have no effect on polluting the interior and re-released pollutants. Function, large limitations when used; ammonia derivative type, nucleophilic addition reaction with formaldehyde, but excessive use will cause ammonia pollution, cause secondary pollution and not easy to remove; amino acid type, amino acid and formaldehyde react to form polymer compounds, However, there are problems such as insufficient response, incomplete removal, and low efficiency.

Abstract

The invention discloses a negative ion biomass aldehyde removing agent. Through combination of natural herbal plants and combination of biomass raw materials and negative ions, the negative ion biomass aldehyde removing agent utilizes raw materials having a wide source and low prices and contains a variety of active groups. An amino group and formaldehyde undergo a nucleophilic addition reaction, hydroxyl and formaldehyde undergo an electrophilic addition reaction and an aldehyde substance and formaldehyde undergo an aldol condensation reaction. The formaldehyde reactions are irreversible chemical reactions so that the elimination of formaldehyde is realized, a formaldehyde removal rate is 95% and a sterilizing rate is 95%. The biomass produces glucose and fructose under action of glycohydrolase and the glucose and fructose undergo an aldol condensation reaction with formaldehyde so that formaldehyde is further eliminated. The negative ion biomass aldehyde removing agent is toxic to the human body, does not produce the environmental pollution, acts fast, has durability, has effects of elimination of formaldehyde, air purification, sterilization, disinfection and mosquito repellent, can relieve fatigue, restore consciousness, improve spirit and increase negative ion content of indoor air, is conducive to human health, is produced by simple processes and realizes a low production cost.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an anion biomass aldehyde remover. Background technique [0002] Many household items such as interior decoration materials, furniture, and textiles can release toxic gases such as free formaldehyde, benzene, and TVOC. Formaldehyde is one of the most serious indoor pollution sources, and has been determined by the World Health Organization as a carcinogenic and teratogenic substance; formaldehyde has the longest volatilization period, and its hazards are manifested as strong irritation to the upper respiratory tract mucous membrane, eyes and skin, causing headaches , dizziness and other symptoms, severe respiratory irritation and edema will occur when the inhaled concentration is too high; formaldehyde is one of the important factors that produce diseases such as bad building syndrome and building-related syndrome. [0003] Aldehyde remover is a kind of active organic a...
